It was a patient and well-constructed innings from the 35-year-old, who hit nine fours and two sixes in the 167-ball knock to help put the hosts in a strong position.
Smith also scored a ton at the last Test in Brisbane -- his first since June 2023 -- with the latest his 34th in his 113th match.
It moves him alongside four other players on the all-list of century-makers, including Sunil Gavaskar and Brian Lara.
Only six players have scored more, led by Sachin Tendulkar's 51.
